Water Resistant Design

All new B&D Controll-A-Door openers now feature unique Tri-Tran multi frequency operation. Tri-Tran has an automatic frequency change function, with each of its three frequencies transmitted having a much tighter bandwidth.

The frequency changes every 22mS during a transmission and reception. So if there is another signal interfering on a part of this frequency spectrum, the automatic change ensures the signal still reaches the opener.

This makes Tri-Tran up to one thousand times better, in terms of in band interference rejection, than a typical FM receiver, and up to a million times better than some AM receivers.
